Applicetion fil ed September This invention pertains to automobile bumpers. and in general my object is to provide an improved construction and assembly of bumper parts for attachment and use at the rear end of an automobile \vhereefuel tank and the side bars of the chassis frame are partly or wholly covered by aprons and the tormzition' ofth'e chassis framennd presence of n' rt re cnrr er and spare lIEIQ make it diiiicult to vmount a bumper with. conven- V ience end despatch end in a stable protective 1t ition upon the frame opposite and relatively close to the mud guards or wheel Fig; 3 is a perspective view of the bumper V :itseli' Without its supporting fitting.
